BOTTLE-CAPPING MACHINE.

SPEGIFIGATION forming part of Letters Patent No. 703,203, dated June 24, 1902.

Application filed March 26. 1902- Serial No. 100,036. (N0 model.)

To CLZZ 1071/0727 it nuty concern;

Be it known that I, OSCAR HEYMAN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bottle-Capping Machines, of which the following is a specification.

' My invention relates particu-larly-to improvements in machines whereby caps or capsules are applied to the necks and heads of bottles, and its objects are, among others, to provide a simple and easily-operated mechanismof this character which will securely apply the said caps or capsules and which may be used for applying the same to bottles of varying length and diameter of neck.

It consists of the combination and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical cross-section of the elastic sleeve and cylinder within which the same is located, taken on the line 1 1 of Fig. 2. Fig. 2 is a vertical longitudinal section of a bottle-capping machine, showing my im-.

provements. Fig. 3 is a like section ofthe sleeve, cylinder, and plunger, showingthe use of a plunger of different length. Fig. 4 is a plan of the outer cylinder.

The cylinder A is adapted to receive the elastic sleeve B, which fits snugly therein, and also the sliding plug 0, which has a conical depression 0 at its rear end adapted to receive the end D of the plunger-rod D. At its rear edge the cylinder is provided internally with an annular boss A, which prevents the plug and sleeve from passing out therethrough. At its outer end the cylinder is provided with a, removable cap E, having a central opening E, of lesser diameter than the elastic sleeve B and adapted to hold the said sleeve in position and prevent it from leaving the cylinder when pressure is applied at the rear end thereof. The edges E of the cap, against which the sleeve abuts, are beveled, so that the tendency of the edges of the sleeve will be to wedge themselves into the corners thereof when the pressure is applied. The cap E is removably secured to the cylinder by the lugs E which are preferably four in number and pass through the openings .A in the annular rib A of the cylinder leading to the groove A and hold the said cap by coming in contact with the, rib. The rib is provided with beveled portions a adjacent to the openings therein, which will cause the cap to be pressed tightly against the end of the cylinder when the'same is rotated and the lugs E caused to slide along the same. The cap is also provided with a handle E, by which itmay be turned and which affords a suitable leverage for tightening the same. The cylinder is preferably made integral with the bed-plate F, which is provided at its opposite end with standards F, to which the lever G is pivotally secured'by means of the bolt G. A short distance from the pivot-bolt G the rod H is secured to the lever by means of the bolt H, so that when the lever is drawn forward the bolt, together with the sleeve I and theplungenrod D at the other end of the sleeve, is thrust forward. The sleeve I is interiorly threaded at its rear end to receive the threaded outer end of the bolt 11, while its other end is adapted to receive the rear end D of the plunger D, which is of reduced diameter. A partition I is provided at or near the center of the sleeve 1, against which the rear end of the plunger D abuts. The plungers D may be made of different lengths to accommodate different lengths of the rubber sleeves which are used, according to the length and size of the bottle-neck upon which the cap is to be placed. This is desirable, owing to the fact that unless the head of the bottle is pressed against the sliding plug C while the cap is being applied the said cap will have a tendency to bulge or wrinkle at the top.

The operation of this device is as follows: The cap or capsule J is first placed loosely over the neck of the bottle and the said neck then introduced into the rubber sleeve B. The lever Gis then drawn forward and downward, causing the plungerD to press against the sliding plug 0 and move it forward. This movement compresses the rubber sleeveB, causing it to expand inwardly and press the said capsule tightly around the head and neck of the bottle. Longitudinal grooves B are provided on the interior of the sleeve to admit of this inward expansion and also to take up the slack in the capsule when it is pressed around the bottle-neck. This will leave a small rib or fold corresponding to the grooves on two sides of the cap, which may be flattened down by turning the bottle partly around and applying the pressure again.

Alimited adjustment of the plunger to vary the pressure upon the bottle-neck may be obtained by rotating the sleeve I, and thus cause the plunger to approach or recede from the plug 0, and by the use of this adjustment bottles having necks of varying diameter may be capped without necessitating the use of different-sized sleeves.

What I claim is- 1. In a device of the character described, the combination of a cylinder, an elastic sleeve fitted therein, a removable .cap on the end of said cylinder, a central opening in said cap of lesser diameter than the bore of the cylinder, a portion of said cap, extending from the said opening to the inner surface of the cylinder, inwardly beveled, and means for causing the said sleeve to be pressed against the said beveled portion.

2. In a device of the character described, the combination of a cylinder, an elastic sleeve therein, a removable cap, a central openingin the said cap, a sliding plug within the said cylinder, aplunger having one end in contact with the said plug a sleeve into which the opposite end of said plunger passes,

an interior threaded portion of said sleeve at its opposite end, and a rod threaded therein and means for causing the said rod to reciprocate.

3. In a device of the character described, the combination of a cylinder, an elastic sleeve fitted therein, acap on the end of said cylinder, a central opening in said cap of lesser diameter than the bore of the cylinder, and an inwardly-beveled portion of said cap extending from the central opening to the inner surfaces of the cylinder, and means for causing pressure upon the end of the said sleeve opposite the cap.

4. In a device of the character described, the combination of a cylinder, an elastic sleeve therein, a cap on the end of said cylinder, a central opening in said cap, a slid 1902, at the'city of New York, county and State of New York.
